Plasticity-creep interaction effect was experimentally investigated under changing temperature. The combined stress tests were performed on thin-wall tubular specimens of austenite stainless steel SUS 304 from room temperature to 600℃. Plastic behaviors at 600℃ subsequent to creep pre-strain produced at room temperature and those at room temperature subsequent to creep pre-strain produced at 600℃ were experimentally determined under various loading conditions. The stress strain relations obtained by these experiments were compared with the results calculated by the equiplastic strain surfaces. The influence of creep pre-strain at room temerature on subsequent plastic behaviors of high temperature was nearly equal to that of plastic pre-strain, but the influence of creep pre-strain at high temperature on plastic behaviors of room temperature were weaker than that of plastic pre-strain.
